Question

Solve for the unknown 8k-2k=42

Answer 1

k = 7

Step-by-step explanation

The unknown variable in this equation is k,

`8k-2k=42`

To find its value, first, we have to combine like terms. This means that on the left side of the equation, we have to combine the coefficients of k,

`\begin{gathered} (8-2)k=42 \\ \\ 6k=42 \end{gathered}`

And then, divide both sides by 6,

`\begin{gathered} (6k)/(6)=(42)/(6) \\ \\ k=7 \end{gathered}`

Hence, the value of k is 7.
